It was pretty good until past 50mm, I feel sorry for the final KO. I must say I am disappointed. there are many zoom perform much consistent over the range like Canikon and sony zeiss 24-70 f2.8. even 24-105, 24-120 F4 Canikon. Consider this is a f4 APS-C

Realistically, about 80%, I would say we use WA for landscape which require corner, and tele for people, which is not. But This is not a lens made history but just another Sony zoom.

Unless the copy variation?

Edit: color is nice though, I bet flare performance good too from its clarity, but I know that already, the famous T* coating works

Can you make some on one of those wierd steps between f8 and f11? Im for example using f9 quite a bit with my old zoom lens.. cause f8 is sharp but not that much DOF and not "perfectly even" but f11 is starting to be too soft.

Otherwise, I think it really is close to old 16-80. How much CA does it have without using CA removing? Btw. is it distortion corrected or not? (that could actually explain those corners too)

If you cant check it, just upload few RAW files (16, 28, 35, 50, 70 @ f9 or so). I can check it and see what I can squeeze out of it.

i believe the 18-55mm has field curvature that curves inward while the new zeiss has field curvature that curves out (at least at the wide end).

i had the same thought

The charts on page 1 are taken without CA correction, i would say better than the kit but not by much.

Distortion isn't corrected.

here are some "real world" images, mostly at f9. If you would like to see the raw just send me an email @ reeve.phillip@gmail.com
